The Role of Glass Fiber in GRC: Enhancing Durability, Precision, and Quality Control
Why Glass Fiber Matters in GRC Glass Fiber Reinforced Concrete (GRC or GFRC) is an advanced composite material widely used in architecture, landscaping, and urban furniture. Its performance relies heavily on alkali-resistant (AR) glass fiber, which gives GRC its characteristic balance of flexibility, durability, and formability. By using the right type and dosage of glass fiber, manufacturers ensure that products like GRC planters, cladding panels, and outdoor furniture meet strict mechanical and aesthetic standards. Durability in Outdoor Environments AR glass fiber resists corrosion in cement’s alkaline environment, providing long-term structural integrity even under: Intense UV radiation, Wet/dry cycles, snow, and freeze-thaw conditions, Aggressive urban or marine environments. This makes GRC a reliable, low-maintenance material for long-lasting outdoor installations. Why Alkali-Resistant (AR) Glass Fiber Is Essential -Resistance to Cement Chemistry AR glass fiber is engineered with high zirconia content (≥16.5%) to withstand the high alkalinity of cement paste. Without this, ordinary
